My invention relates generally to glass presses and their molds and has for its principal object, to provide simple, practical 'and convenient means for manipulatingfthe mold for the purpose of accomplishing, with comparatively little effort on lthe part of the operator, the turning outl or removal and discharge of the molded ware or articles, from the said cavities.

'0n certain types of 'glass presses havin-'g large 'and heavy molds, the manual manipulation of the latter in the turning out of the molded ware involves considerable arduous labor and effort on the part of the operator and it is one of the prime objects of my invention, to provide means for minimizing such tiresome operations and at the same time, increasing production of the molded products.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which:

Fig. 1 is a side elevation of a glass press and showing my improved mold manipulation means applied thereto.

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1.

Fig. 3 is a side elevation similar to Fig. 1 and showing the lower part of the mold drawn forwardly into position to be inverted so as to turn out the ware.

Fig. 4 is an elevational view of a modified form of a part of the mold supporting means.

Referring by numerals to the accompanying drawings, which illustrate a practical embodiment of my invention, I designates the bed plate of a conventional glass press, II spaced uprights which support and guide the vertically movable upper part I2 of the mold, I3 the lower part of the mold which is movable on bed plate I0 and which, when positioned against guides and stops I4 on said bed plate, occupies a' position directly beneath the upper mold part l2.

Usually these guides and stops are adjustable in order that the lower mold member I3 may be accurately centered beneath the upper member.

Secured to and projecting from lower mold member I3 is a member, preferably a rod I5 which functions as a guide for said mold member and at the rear of bed plate I0, said guide passes through an aperture I6 formed in a bearing I1, the latter` being fixed to said bed plate.

Secured to guide I a short distance from said member I3 is a small disc I8, which during the 5 Claims. (Cl. 49-41) 2 turning 'out operation, functions as a wheel 'to 'travel 'over the upper 'face of the .bed plate and the diameter of this disc is 'such that its periphery or tread just clears the surface of 'the bed .plate when lower'mold member 1'3 is resting thereen (see Eig 1.);

AThe rear portion vsuch as 'Ilia of 'guide l5, is preferably, although .not necessarily, 'inclined 'up'- wardly .a 'iew degrees and 'secured on the rear end of said inclined portion is a collar I9, which serves as a stop to limit the forward movement of the guide through bearing I 1.

Secured to and projecting outwardly from the front side of mold member I3 is a handle 20.

During the glass pressing function, mold member I3 is centered on bed plate ID beneath member I2 and the latter moves downward onto the lower member thus pressing molten glass into the mold cavities. Following this operation, mold member I2 moves upwardly and to effect .a turning out of the pressed ware from the cavities in lower member I3, handle 20 is engaged and lower member I3 is drawn outward to a position in front and clear of bed plate I0 and as said member clears the front edge of the bed plate, disc lowers a fraction of an inch until it contacts with and rests upon the surface of said bed plate, thus supporting the lower mold member without ellort on the part of the operator.

By means of handle 20, lower member I3 is turned upside down, during which movement, disc I8 functions as a wheel to travel laterally a short distance on bed plate I Il, thus serving as a rolling support and the bottom of the inverted mold member is now tapped in the usual manner to loosen the ware from the mold cavities, which Iware drops into a suitable receptacle.

When the lower mold member is drawn outwardly to turn out the Ware as just described, the inclined rear portion I5a of the guide I5 bearing in bearing I1, slightly elevates the forward end of said guide and mold member I3 (disc -I8 serving as a fulcrum), so that when said member I3 is turned right side up, its underface occupies a plane slightly above the upperface of the bed plate thus enabling said member to .be moved rearwardly onto said plate, without the arduous effort of bodily lifting said member.

Subsequent to the operation just described, a mass of molten glass is placed in the cavities of lower member I3 and same is now slid with comparatively little effort rearwardly on the bed plate, to its centered position to receive the upper mold member for the subsequent pressing operation.

V22, which slides readily over the surface of the Vbed plate.

Thus itwill be seen that I have provided a Vglass press mold turning out device which is simple in structure, inexpensive of manufacture and very eifective 'in performing the functions for which it is intended. Y

It win be understood that minor changes in the size, form and construction of the various parts of my improved glass press mold turning out dethe spirit ofthe inventiornthe scope of which is Y gaging Vsupport carried by said guide member, and located between said bearing and the lower part 4of the mold.
